    • n swietenia A genus of polypetalous plants, of the order Meliaceæ, type of the tribe Swietenieæ. It is characterized by flowers with five petals, a ten-toothed urn-shaped stamen-tube, annular disk, and numerous pendulous ovules, ripening into broadly winged seeds with fleshy albumen. There are 3 species, natives of Central America, Mexico, and the Antilles. The chief of these, S. Mahagoni, a large tree furnishing the mahogany of commerce, extends in a reduced form (50 feet high or under) to the Florida keys. It bears smooth abruptly pinnate leaves composed of obliquely ovate tapering opposite leaflets. The small flowers are borne in axillary and subterminal panicles, and are followed by five-celled septicidal capsules. See mahogany.
